Abstract
Influence of recreational loads on condition and phytodiversity of beech forest ecosystems in Opillya (Western Ukrainian Steppe-and-Forest zone) which are located at the northeastern border of their area of distribution was assessed. Beech forests are relic phytocenoses of Middle Holocene and need special conservation regime and establishment of monitoring. Recreational changes in beech forests ecosystems are displayed in compaction, insolation and xerophytization of surface soil layers, reduction of thickness and stock of forest litter, disturbance in the water provision regime, trophic regime (reduction of the content of humus and mobile nitrogen and phosphorus) and edatope aeration regime; increase of tree number with considerable mechanical damages of stems, spread of contagions, reduction of stand density and tree quantity, disappearing of main tree species undergrowth, reduction of species diversity in shrub layer, structural transformation of herbal layer on species and phytocenotic levels of organization against background of insignificant variation in its diversity according to Shannon-Weaver index, invasion and naturalization of adventitious plant species.
